Bicycle kit costs are $750??

[offroad1994]

So I was looking at the bicycle hub kit costs for a 26 inch wheel. Ebay has them priced out for $600 plus $60 shipping. This does not include batteries which I would suspect would cost $100.

Grand total for electric bicycle conversion is around $750. That sounds pretty expensive.

********

Are there less expensive ways to convert a bicycle with a DIY kit?

Here is a less costly kit solution for $400. Any reviews from folks??

Here is a kit for $450 that has absolutely everything

Also notes: Need to try to get a brushless motor for efficiency. Also need to be aware that there are three kinds of Lithium-ion batteries. Get the wrong lithium battery and it will be dead in 200 cycles.

These look interesting too

My bolt-on kit in 2001 cost $350. lead acid batteries too (no longer being sold). 2 years later- lithium battery - $1000. In 2006 a hub motor with 3 batteries cost $1350. Getting very expensive! Happy I got in on the ground floor.

Anybody know anything about these?

Sounds perfect for my dad, I've got some old e-scooter batteries on his bike now.

Not quite...
Lithium Ion (LIon),
Lithium Polymer (LiPo),
Lithium Iron Phosphate (LiFePo4), and
Lithium Sulfur.

The LiPo's have the best energy density/by weight.(Source)

There are also some new Lithium batteries that are experimental. Fast charge 1000 cycle technology. maybe five years away.

When I look at the total of batteries (LiFePo + charger) and the hub (500W brushless) with control electronics I still get $750 combined.
